| Abstract: |
| The influence of soil moisture on the growth, fruit shape, fruit quality and water use efficiency of greenhouse cherry tomato (Lycopersicon esculentum Mill) was studied to select the the optimum soil moisture in order to provide basis theoretical support for rational watering in cultivating process of greenhouse cherry tomato. Ruby cherry tomato was used as the object of study by five soil moisture levels (with field capacity of 40%～50%, 50%～60%, 60%～70%, 70%～80% and 80%～90%) to measure the change rule of plant growth, fruit quality, yield and water use efficiency. The results indicated that the highest output was 6.25 kg/m2 when the most hydrates were accumulated of greenho
use cherry tomato in the field capacity of soil moisture content 70%～80% conditions. When soil moisture accounted for 60%～70% of the field capacity, every quality indicators reached the maximum: ie. Vc 652.2 mg/kg, soluble sugar 72.8 g/kg
, and dry matter content 71.8 g/kg respectively. The proportion of soluble solid was 9.8% and water use efficiency in the conditions was also the largest (13.9 kg/m3). Taking into consideration of the effects of soil moisture on the growt
h, fruit quality, water utility efficiency and fruit yield, the field capacity of 60%～70% could be used as an ideal soil moisture indicator of greenhouse cherry tomato. |
